摘要: 为了充分考虑多种评估参数以提高结构损伤评估的准确性,应用可拓学理论和方法,给出钢筋混凝土结构地震损伤的经典域物元和节域物元;以整体损伤指数、最大层间位移角、滞回耗能循环次数和楼层能量集中系数作为物元,建立了损伤评估的物元模型;提出了基于物元模型的钢筋混凝土结构地震损伤综合评估方法.该方法可通过结构推覆分析和能力谱方法实现,并且全面考虑位移和能量等多种基于性能设计的因素.通过计算示例说明了该方法的应用步骤,并对该方法的合理性和有效性进行了验证.Abstract: The theory and method of extenics were applied to establish classical field matter elements and segment field matter elements for reinforced concrete structure. A matter-element model for structure wes established based on four matter-elements, which were internal damage index, maximum inter-storey drift, number of inelastic cycles and energy-concentrated quotient. A matter-element analysis method for seismic damage evaluation on reinforce concrete structure was presented. This method can be accomplished by nappe structure analysis and capacity spectrum method, while considering multiple factors for performance-based design, such as displacement and energy. This method was verified clearly through the practical example, and the rationality and validity were demonstrated. By this practice example, the model proves to be accurate and logical in e-valuating the degree of structural seismic damage.
